Craftsman Air Tools & Compressors - Recent Questions, Troubleshooting & Support
3gal. aircompressor - craftsman model #921153101
This problem is not uncommon with small compressors and the inexpensive plastic regulators they use nowadays. The one surefire way to stop it is ti install in in-line valve before the regulator outlet, even if it involves the double ended & threaded brass soupler so they both fit on. This way you can just turn the handles across the line effectively shutting off air flow. I have two pancake compressors and ended up doing the very thing.
Then when time comes to hook up a hose and tool, just switch the handle back and you have air.

Craftsman 33gal.150 psi air compressor:Start on M/T tank not when full. Start & builds up; then drops down to cut in pressure & kicks breaker when starting up.What can I do to fix this problem.
Sounds like you need a higher current circuit. When a motor starts up, there is a higher than normal current draw, usually 2x to 4x the running current. When it starts up against cut in pressure, there is even more resistance and hence more current draw than when starting up against no pressure in the tank. So, your circuit is capable of providing startup current with no presure, but with pressure it is drawing more current and tripping the beaker. Don't just put a higher rated circuit hreaker in unless you want to buern down your house. Get an electrician to measure the starting current of your compressor and wire up a circuit and outlet that will handle that current safely. That said, the advertising for the compressor says it can run on a standard (15 amp) household circuit, so your motor may be drawing excessive current. Either way, an electrician can help you. Another option is to add capacitive start to the compressor, but, again, a good electrician will have the solution.
